Shapes and colors

The iris

Iris is a genus of rhizomatous or bulbous perennial plants in the Iridaceae family. The genus Iris contains 210 species and countless horticultural varieties. Horticultural hybrid Irises are often found in gardens, mistakenly called Germanic Irises. Like many flowering plants, the first irises appeared in the late Cretaceous (Campanian) around 80 million years ago in an area that is now Antarctica. Irises are now found throughout the northern hemisphere, in Europe as well as in Asia, North Africa and North America. The garden of the irises of the castle of Vullierens, near Morges, offers magnificent walks.

The coulor pencils

For this series I wanted to represent the primary, secondary and complementary colors as well as the Itten chromatic circle. There are several qualifications, possible definitions of colors depending on the area covered, painting, printing, screens. Additive synthesis or subtractive synthesis among others define different primary colors. The opposition of greens and reds together with those between yellows and blues and between black and white forms the basis of human color perception, formed from the ganglion and bipolar nerve cells in the eye. These six colors are the elemental colors of Hering. I worked particularly on the depth of field in order to get, I hope, original photos.


Orchids or Orchidaceae (Orchidaceae), form a large family of monocotyledonous plants. It is one of the most diverse families, counting more than 25,000 species, divided into 850 genera. In this gallery there are only three. It is a widely distributed family; the majority of species are found in tropical regions. The name comes from the genus Orchis, a Latin word derived from the ancient Greek “testicle”, in reference to the shape of the underground tubercles of certain terrestrial orchids from temperate regions, when these tubercles are paired. It is to Theophrastus that we attribute this name.
